Application August 12, 1932, Serial No. 628,453

4 Claims. (01. 261-403) This invention relates to air cooling devices,systems, or arrangements adapted to lower the temperature in rooms,plants or the like by water cooled air, and it is the principal objectof my 5 invention to provide a device of this character which iscomparatively simple and inexpensive in its construction, yet durableand highly elicient in operation.

Another object of my invention is the provi- 19 sion of an air coolingdevice in which a plurality of frames holding water absorbing materialare suitably arranged within a box or casing and are subjected to theinfluence or action of a current of .air.

A further object of my invention is the provi-- sion of an air coolingdevice of this type equipped with a suction pump delivering the waterpumped from a suitable tank in suitably divided streams to the clothframes, while the surplus of water is returned into the tank.

with the cooling air which is led against the moistened cloth or fabricsheets, and the motor driving the wind wheel or turbine issimultaneously adapted to drive the pump.

These and other-objects and advantages of my invention will be morefully described as the description thereof proceeds and will then bespecifically defined in the appended claims.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a top plan view of an air cooling arrangement constructedaccording to my invention.

Fig. 2 is a sectional front elevation thereof. Fig. 3 is an end view,partly in section on line 3'3 of Figure 2.

Fig. 4 is a perspective view of a frame box.

Fig. 5 is a perspective view of one of the frames.

As illustrated, in a casing 10 of suitable size and material a suctionpump 11 is arranged adapted to be driven from a motor 13 on a support 12by means of a suitable belt.

A turbine, or wind wheel 15 is mounted on the shaft of the motor 13 andis inclosed within a sheathing case 14. This turbine, actuated by themotor 13, drives air into a wind box 16 which discharges into a chamber19. Within the said chamber 19 frames 17 are arranged in spaced relationto each other and supported-by notched elements 18 which project fromthe walls of the chamber 19. These frames are held in position at theirlower extremities by frictional contact with the walls of the saidchamber. Pieces of linen, or water absorbing material 18 are held, orspread in the frames 17. A pipe conduit 20 carries water from a tank 21to the pump 11 which forces the said water upward through the pipe 23 todischarge into a distributing pipe 24 which is set within the casing 10and passes over the holding frames 1'7 and the linen, or water absorbingmaterial therein supported. The pipe 24 is provided with a plurality ofnozzles- 25 through which water passes to moisten the said waterabsorbing material. Surplus water is led back into the tank 21 throughcollecting grooves 26 which are arranged below the absorbing material,the final discharge being through the nozzle 27.

Water is filled into the tank by means of a filler nozzle 22, while itcan be drained through the drain cook 28. The casing is supported bysuitable feet 29 and a felt mounted cover 30 or the like can be employedto close the casing when not in use.

In operation, the motor is started to operate the pump driving Waterfrom the tank to the upper part of the casing for distribution onto thefabric sheetson their frames through the nozzles 25. As the sheets arearranged in suitable frames 17 supported in the notch elements 18' theymay readily be exchanged for cleaning and other purposes by lifting thesaid sheets and frames out of the casing. The motor will drive the windwheel or turbine to drive air through the wind box against the moistenedsheets where the air is cooled and then distributed into a room to becooled through the opening in the top of the easing 10 when cover 30 isremoved. The surplus of water is collected in grooves 26 and returned bymeans of the nozzle 27 into the tank, which can be supplied with waterthrough nozzle 22 or drained through cock 28. The frames being arrangedin an inclined position in their box will compel the air current to passthrough them to thoroughly moisten the air. 7

It will be understood that I have disclosed the preferred forms of mydevice only, as one example, of the many possible ways to practicallyconstruct the same, and that I may make such changes in its generalarrangement and in the construction of the minor details thereof as comewithin the scope of the appended claims without departure from thespirit of my invention, and the principles involved, so for instance Imay make my device useful also for the winter to heat the air by forinstance the building in of a suitable electric heating element or thelike.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. In an air cooling device, a casing having an upper opening, a motordriven suction pump in said casing, a wind box, a turbine wind wheeloperated from said motor to drive air through said wind box, a chamberabove said wind box, a plurality of frames, pieces of moisture absorbingmaterial spread between bars of the said frames, said framesexchangeably supported in notch elements in said chamber, a pipe havinga plurality of nozzles arranged in said chamber above the frames, awater tank, a pump, pipe connections between said tank and said pump,and between the said pump and the nozzles through which the water ispumped to moisten the material held in said frames, said chamber havinga plurality of water collecting grooves in its bottom and a nozzlethrough which the surplus of water collected in said grooves is returnedinto said tank, and a felt lined cover over the said upper openingthrough which moistened air is driven by the operation of said windwheel into a room to be cooled.

2. In an air cooling device, a casing, a chamber mounted within the saidcasing, a distributing pipe set over the said chamber, nozzles in thesaid pipe directed downwardly over a plurality of water absorbing pieceswhich are hung in frames supported in notch elements attached to wallsof the said chamber, collecting grooves positioned below the said waterabsorbing pieces and inclined to discharge into a water tank thereunder,a wind box opening into the aforementioned chamber and the said boxconnected to receive air from a turbine which is actuated by an adjacentmotor, a pump connected to be driven by the said motor and the said pumpconnected to draw water from the aforementioned tank and to force thesaid water through a pipe which discharges into the distributing pipe inthe upper portion of the said chamber.

3. In an air cooling device, a supporting casing, a water tank mountedin conjunction therewith, an air driving turbine mounted within the saidcasing and actuated by an adjacent motor, a wind box connected toreceive air from the turbine and to discharge the said air into an upperchamber where it contacts with water absorbing pieces which are hung inframes supported in spaced relation to each other from notch elementsattached to the walls of the said chamber, a water distributing pipe setabove the said frames and having nozzles directed toward the waterabsorbing pieces, an opening in the supporting casing over the saidchamber and a felt lined cover set over the said opening, a pump,actuated by the aforesaid motor and the said pump connected to drawwater from the aforesaid tank and to force the said water up through apipe and into the distributing pipe, and collecting grooves positionedbelow the water absorbing pieces and the said grooves directed todischarge into the aforementioned tank.

4. In an air cooling device, a supporting casing, a water tank withinthe said casing, a wind box positioned in the lower portion of thecasing and opening upwardly into a chamber in which are removablymounted a group of water absorbing elements, a grooved structure setbelow the said elements and inclined at an angle directed toward adischarging nozzle leading into the aforesaid tank, an opening in thesupporting casing over the aforesaid chamber, a felt-lined covering overthe said opening, a turbine set to drive air into the wind box,conducting means to carry water from the tank and to distribute the saidwater from the tank and over the absorbing elements, means to actuatethe said turbine, and means to force the water through the, conductingmeans aforementioned, substantially as shown and described.
